Snow Plowing 570 or 850 ??

I had a 2013 Sportsman 550 EPS but sold it to my father-in-law. I then purchased a 2020 Can-Am Outlander XT 650 which, I also recently sold. I just wasn't happy with some of the features. I was pleased with the twin-cylinder power tho... I plan to purchase a new Sportsman before spring and I plan to plow snow with it in the winter. I live in Northern Maine and we get a decent amount of snow. My driveway is about 150ft long.

Should I get the 850, or will the 570 be enough to handle plowing all that snow?
